Dan has written a thoughtful essay that tries to help us learn from accidents and extreme, intentional accidents (= terrorism). He looks at Charles Perrow’s Normal Accidents and the 9/11 Commission Report (which he has excerpted helpfully here). Dan draws too many insights to summarize, but the need for providing flexible, two-way communication systems so that non-officials can act effectively leaps out at me.

(By coincidence, Dewayne Hendricks today talked about how a couple of strategically positioned repeaters were able to provide a forest fire command center with wifi communications access.)
